Hi people,
I'm trying to figure out why the unwarping method only adds the VDM to the y-coordinates. Does the x-coordinates remain unchanged in the resulting EPI image? I mean, pixel displacements in each slice have 2 degree of freedom (in x and y) and in the program, the VDM only affects to y coordinates.
In SPM8 toolbox:
Line 1805 (aprox.) in Fieldmap.m:
uepi = reshape(spm_sample_vol(IP.epiP,xyz(:,1),...
xyz(:,2)+tvdm(:),xyz(:,3),1),IP.epiP.dim(1:3));% TEMP CHANGE
Thank you very much in advance.
